Product Description

Bosch Rexroth is a renowned manufacturer of industrial automation products and motion control accessories.

The HMF01.1N-N0K1-M0215-N-690-NNNN is a motor filter produced by the company. This device allows the use of V/f mode with non-converter proof motors. The motor filter can reduce leakage current and voltage stress to low levels. Servo motors are driven using three-phase pulses that have sharp edges with very high frequency. These high frequency signals are not effectively controlled by the motor’s capacitive coupling because of low impedance. As a result, there is a high frequency voltage on the rotor and subsequent ground current through motor bearings. The high frequency voltages eventually cause deterioration of the motor bearings. The HNF motor filter is capable of modifying the sharp edges of these high frequency pulses. The motor filter is able to increase the impedance and decrease unwanted currents as a result.

The HMF01.1N-N0K1-M0215-N-690-NNNN presents a cost effective solution to electromagnetic interference issues of servo motors. The motor filter is able to substantially reduce the ground current in motor bearings. Overall high frequency noise in tools is also reduced with this device. It can be installed easily and requires no maintenance while leaving a small footprint. This motor filter is very effective in reducing high frequency electrical noise. Electrical noise is known to cause data errors, undesirable equipment behavior, and equipment lockups. The normal operation of machines can be disrupted and sensor data can be altered if an appropriate motor filter is not used. This model is also used for reducing electrical overstress that can affect the performance of pick-and-place tools in assembly lines, wire bonders in semiconductors, and IC handling tools. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
